Alumina Bifold



The unique aluminium bi-folding door system with beautifully sculptured frames and optional foiled finishes, spanning apertures up to 6.5m wide and sashes 2.5m high.

A new-generation, technically advanced aluminium bi-fold system, Alumina has been designed by the same team as the innovative Liniar window suite.

Alumina is a highly distinctive sculptured bi-fold door, combining superb aesthetics, unparalleled quality and the utmost security to add uncompromising style to any property.

As you would expect, Alumina is fully accredited to Secured by Design, PAS24 and BS 6375. Alumina is compliant with Part Q, making it deal for new builds, extensions and large scale projects.

The only foiled aluminium bi-fold on the market, Alumina matches perfectly with Liniar PVCu windows, with the foils offering a unique warm touch finish.

Alumina’s strength and size makes it ideal for a wide range of projects, from extensions and self builds to large scale commercial use.

With U-values as low as 1.2W/m²K, Alumina also offers higher thermal efficiency than other aluminium bi-folding doors, thanks to its innovative patented thermal lock – helping to keep more of the heat inside your property, reducing energy bills.
